  2. The discuss starts from the " positive externalities " of tech - research and development, pointing out that the products of tech - research and development somewhat has the property of " public good ". without < wp = 8 > government ' s interfere, the intensity of tech - research and development by private section ca n ' t meet the need of " pareto optism " because of the " positive externalities ", as a result, the items of venture capital are insufficient and the development of venture captal will be pull back. rational policies of government expediture can internalize the " positive externalities " - transforming them to more revenue or less cost of the tech - research and development private suppliers. be feared of the high risk at the beginning of venture capital, the private section ca n ' t provide enough capital, the " capital gap " should be fetched up by government with equity capital, creditor ' s right capital, subcidy, at the same time, some other means, such as government purchase, credit guarantee, capital insurance, tax expenditure can promte private capital, is also important. in this part, the function of the above means, the establishment and enforcment of them are breafly discussed. because tax policies play a critical role in fiscal policy, r - y chart is used to analyse the relation between tax and venture capital, at last, a conclution is drawn : tax expenditure can promote venture capital

    這部分論述從科技研發成果的「外溢性」入手，指出科技研發成果在不同程度上具有「公共品」性質，這種外溢性使得在純市場條件下，私人部門研發活動強度達不到社會資源配置最優的要求，也使風險投資項目來源不足， < wp = 6 >阻礙風險投資的發展。合理的政府財政支出政策可以使「外溢性」內部化。之後，論述了風險投資資本來源與政府財政支出政策的關系，由於風險投資尤其是其初期的高風險性，民間風險資本不足，應由政府以股權及債權投資、補助等財政直接支出方式彌補資本缺口，運用政府采購、財政擔保、保險、貼息、稅收優惠等間接支出方式，鼓勵民間資本進入風險投資領域也同樣重要。

    對于第一個核反應，我們計算了直接俘獲過程以及兩個共振態的俘獲截面和總截面，我們的計算結果顯示，在天體感興趣的溫度范圍內，直接俘獲過程對總截面的貢獻是主要的；對于第二個反應，我們的計算結果與已有的實驗結果符合的較好，其中~ （ 12 ） c （ n ， ） ~ （ 13 ） c的第一激發態計算結果顯示出截面有明顯增大，這從理論上支持了我所關于~ （ 13 ） c第一激發態具暈結構的實驗發現，這是國際上第一次在激發態中發現暈結構。
  8. We consider two situations : ( i ) the light is polarized along the z - direction, in which case the first allowed dipole transition is to the first subband ( nx - 1, ny = 1 ) ; ( ii ) the light is polarized along the x - direction ( paralleled to the transverse cross - section of the wire ). the first allowed dipole transition is to the second subband nx = 2 relative to the x - direction and to the first subband nr = 1 relative to the y - direction of the wire
